Question

I was so familiar with her that I recognized her voice ________ I pickedup the phone.

A．the moment

B．after

C．before

D．while

Answer 1

A

试题分析：考查连词辨析。The moment一…就…；after在…之后；before在…之前；while当…时；句意：对于她的声音我如此熟悉以至于我拿起电话就听出了她的声音。根据句意说明A正确。
点评：要特别注意一些名词或者名词短语转换而成的连词，如the moment, every time等，可以转换成连词引导时间状语从句。
